Rick Carlisle looking forward to challenge

After passing on Andrew Bynum, who decided to join the Cleveland Cavaliers, the Mavs are left trying to find another way to improve their team.

Sources told ESPN.com’s Marc Stein that Dallas is looking at Samuel Dalembert and Greg Oden to fill the need at center.

Even with the uncertainty surrounding the roster, Mavs coach Rick Carlisle didn't seem concerned as the summer league team prepares to head out to Las Vegas.

“It’s July 11. We don’t even have training camp until October,” Carlisle said Thursday. “Who knows what’s going to happen over the next few months?”

It’s hard to paint a rosy picture for the Mavs this summer. Things haven't gone as planned and they are now left scrapping to find pieces to try to build a playoff contender. With their current situation and the roster in a state of flux, shouldn’t that cause some concern or anxiety?

“Isn’t that exciting,” Carlisle immediately replied. “That’s excitement. That’s an enthusiastic thing. Look, it’s exciting to have a group of new guys and be assigned the job to bring them together and get them better.”

It shouldn’t be a radical adjustment for Carlisle, who operated under a similar fashion last season with players such as Chris Kaman, O.J. Mayo, Darren Collison and Elton Brand coming to town on one-year deals. Carlisle has put a positive spin on a situation, noting that time is still on the Mavs' side and that they can still be successful.

“That’s how I approach it,” Carlisle continued. “With that mindset, I think we can do great things. It’s going to be work and I’m looking forward to it."

The Mavs announced earlier Thursday that they signed Gal Mekel to a deal. They are expected to make the signings of Jose Calderon, Devin Harris and Wayne Ellington official in the near future.

“We’ve still got a lot of work to do here. We’ve got some other roster spots to fill, Carlisle said. "You’re going to hear some good names I think in the coming days and weeks that are going to be on our team.”

The trade market will likely also bring an avenue that the Mavs will have to look into over the next few weeks. It will be up to president of basketball operations Donnie Nelson to ensure that they do bring those “good names” to Dallas.

There is certainly some panic brewing, but Carlisle is giving the impression that he isn't concerned.
